forth herein.
BACKGROUND
Field
[0002] The present disclosure relates to a cleaner.
Related Art
[0003] A cleaner is a device that performs cleaning by suctioning
or wiping dust or foreign substances located in a cleaning target
area.
[0004] Such a cleaner may be classified as a manual cleaner which
requires a user to directly move the cleaner, and an automatic
cleaner that drives on its own and does not require a user to
manually move the cleaner.
[0005] In addition, the manual cleaner may be classified as, e.g.,
a canister type cleaner, an upright type cleaner, a handy type
cleaner, a stick type cleaner, etc.
[0006] For example, US Patent Publication No. US2018/0132685A1
discloses a compression mechanism having a dust compression part
compressing dust in a dust bin.
[0007] The compression mechanism may include a dust bin having an
opening, a filter purifying air in the dust bin, a shroud
surrounding the filter, a dust compression part disposed to
surround the shroud, a handle operated by a user to move the dust
compression part, and a link connected to the handle.
[0008] When the dust compression part is lowered by an operation
force of the handle transferred thereto through the link, the dust
compression part compresses dust in the dust bin.
[0009] However, according to the related art document, at least a
portion of the dust compression part is located higher than the
opening at a standby position, and thus the dust compression part
is accommodated in the dust bin without guiding a flow of air.
[0010] Therefore, an internal space of the dust bin is reduced by a
thickness of the dust compression part, resulting in a reduction in
the space for separating dust.
[0011] In addition, a lower surface of the dust compression part
compresses the dust stored in the dust bin, and here, if the dust
compression part is located higher than the opening, a distance for
the dust compression part to vertically move for compressing the
dust is reduced to result in a reduction in dust compression
performance.
[0012] Because the dust compression part moves in contact with an
inner circumferential surface of the dust bin, the inner
circumferential surface of the dust bin may be cleaned, but there
is a possibility that dust may be caught between the dust
compression part and the inner circumferential surface of the dust
bin, and in this case, a vertical movement of the dust compression
part is not smooth.
[0013] In particular, when the dust compression part is lowered and
rises in the process of suctioning air and dust through the
opening, there is a problem that dust accumulates on an upper side
of the dust compression part.
[0014] When the amount of dust accumulated on the upper side of the
dust compression part is large, a vertical movement of the dust
compression part is not smooth and the dust compression part may
not be able to move to a standby position and block the
opening.
SUMMARY
[0015] The present disclosure provides a cleaner in which air and
dust suctioned through the suction opening fall into a dust bin
even when a movable part is operated downward in a process of
operating the cleaner.
[0016] The present disclosure provides a cleaner in which, even if
dust is present on an upper side of a movable part in a lifted
state after the movable part is moved to a lower side, the dust
present on the upper side of the movable part may easily fall to
the dust bin by air suctioned through the suction opening.
[0017] The present disclosure provides a cleaner in which air
passing through a suction opening at a standby position of a
movable part is prevented from directly moving to an air flow
path.
[0018] To achieve these and other advantages and in accordance with
the purpose of the disclosure, as embodied and broadly described
herein, there is provided a cleaner including a housing including a
suction opening, a cyclone part configured to separate dust from
air introduced through the suction opening, and a dust bin
configured to store the dust separated at the cyclone part; and a
movable part configured to be movable between a first position and
a second position in the housing.
[0019] The movable part may include a frame disposed to surround an
axis of a cyclone flow of the cyclone part at the first position.
The frame may include an air flow path through which air flows so
that dust accumulated in the frame falls from the movable part in
the process of moving to the second position or returning from the
second position to the first position.
[0020] In one embodiment, the frame may include a first body facing
the suction opening at the first position and inclined at a first
angle with respect to a horizontal plane and a second body
extending from the first body and inclined at a second angle
smaller than the first angle with respect to the horizontal plane.
The second body may form the air flow path through which air
introduced through the suction opening flows.
[0021] A bottom surface of the second body may define a lower
portion of the air flow path. The bottom surface of the second body
may be lowered in a circumferential direction. Dust in the air flow
path may flow downward, while flowing in the circumferential
direction.
[0022] A height of the air flow path may increase in a direction
away from the first body, so that a width through which dust flows
is secured so that dust may easily flow through the air flow
path.
[0023] The frame may further include an extension wall extending
upward from an outer end of the second body to define the air flow
path. The air flow path may spirally flow by the extension
wall.
[0024] The frame may further include a third body extending in the
circumferential direction from the second body and inclined at a
third angle with respect to the horizontal plane.
[0025] The first body may be inclined to the outside upward from a
lower side toward an upper side and the third body may be inclined
to the outside downward from the upper side toward the lower side,
so that dust may move downward along the third body.
[0026] The frame may further include a fourth body extending in the
circumferential direction from the third body and inclined at a
fourth angle with respect to the horizontal plane, wherein the
fourth angle may be greater than the third angle.
[0027] A radius of an outer end of the fourth body based on the
center of the frame may be smaller than a radius of an outer end of
the first body.
[0028] A distance between the fourth body and an inner
circumferential surface of the housing is larger than a distance
between the first body and the inner circumferential surface of the
housing, and thus dust on the air flow path may fall downward
through a space between the fourth body and the inner
circumferential surface of the housing.
[0029] Alternatively, the frame may include a third body extending
from the second body so that air or dust flowing through the air
flow path falls downward.
[0030] A distance between a point of the third body and the inner
circumferential surface of the housing may be greater than a
distance between the second body and the inner circumferential
surface of the housing.
[0031] The frame may further include a fourth body extending from
the third body, an inclination angle of the fourth body with
respect to the horizontal plane may be greater than an inclination
angle of the third body, and a distance between one point of the
fourth body and the inner circumferential surface of the housing
may be greater than the distance between the third body and the
inner circumferential surface of the housing.
[0032] The cleaner may further include an air guide located in the
housing, wherein the frame may be disposed to surround the air
guide at the first position.
[0033] The air guide may include a guide wall disposed to surround
the axis of the cyclone flow, the first body may be in contact with
the guide wall, and at least a portion of the second body may be
spaced apart from the guide wall and the air flow path may be
located in a space between the guide wall and the second body.
[0034] The first body may be disposed to face the suction opening,
so that air introduced through the suction opening may be prevented
from flowing directly to the air flow path.
[0035] The cleaner may further include a filter part configured to
filter dust from the air introduced through the suction opening in
the housing.
[0036] The movable part may further include a cleaning part coupled
to the frame and configured to clean the filter part when moving
between the first position and the second position.
[0037] The frame body may further include a third body extending
from the second body and a fourth body extending from the three
body so that air or dust flowing through the air flow path may
smoothly fall downward.
[0038] A distance between the fourth body and the inner
circumferential surface of the housing may be greater than a
distance between the third body and the inner circumferential
surface of the housing.
[0039] With respect to the horizontal plane, the third body may be
inclined at a third angle and the fourth body may be inclined at a
fourth angle greater than the third angle.
[0040] In another embodiment of the present disclosure, there is
provided a cleaner including a housing including a suction opening;

the suction opening and spaced apart from an inner circumferential
surface of the housing; an air guide configured to guide the air
passing through the filter part to a suction motor for generating a
suction force; and a movable part configured to be movable between
a first position and a second position in the housing.
[0041] The air guide may include a first guide wall spaced apart
from the inner circumferential surface of the housing, and the
movable part may include a frame disposed to surround at least a
portion of the first guide wall at the first position.
[0042] The frame may include a first body in contact with the first
guide wall and inclined at a first angle with respect to a
horizontal plane and a second body extending in a circumferential
direction from the first body and inclined at a second angle
smaller than the first angle with respect to the horizontal
plane.
[0043] The second body may be spaced apart from the first guide
wall, and an air flow path may be provided between the first guide
wall and the second body.
[0044] A height of the air flow path may increase in a direction
away from the first body.
[0045] The cleaner may further include: an extension wall extending

[0046] The frame may further include a third body extending in a
circumferential direction from the second body and inclined at a
third angle with respect to the horizontal plane.
[0047] The first body may be inclined upward toward the outside
from a lower side to an upper side, and the third body may be
inclined downward toward the outside from the upper side to the
lower side.
[0048] An inclination angle of the second body may be varied in the
circumferential direction. The third angle may be greater than an
inclination angle at a point of the second body.
[0049] The frame may further include a fourth body extending in a
circumferential direction from the third body and inclined at a
fourth angle with respect to the horizontal plane. The fourth angle
may be greater than the third angle.

DETAILED DESCRIPTION OF THE DISCLOSURE
[0112] Reference will now be made to the exemplary embodiments
illustrated in the drawings, and specific language will be used
here to describe the same. It will nevertheless be understood that
no limitation of the scope of the invention is thereby intended.
Alterations and further modifications of the inventive features
illustrated here, and additional applications of the principles of
the inventions as illustrated here, which would occur to a person
skilled in the relevant art and having possession of this
disclosure, are to be considered within the scope of the
invention.
[0113] As used herein, a term "or" is intended to mean an inclusive
"or" rather than an exclusive "or." That is, unless specified
otherwise, or clear from context, "X employs A or B" is intended to
mean any of the natural inclusive permutations. That is, if X
employs A; X employs B; or X employs both A and B, then "X employs
A or B" is satisfied under any of the foregoing instances. In
addition, features described with respect to certain embodiments
may be combined in or with various other embodiments in any
permutational or combinatory manner. Different aspects or elements
of example embodiments, as disclosed herein, may be combined in a
similar manner.
[0114] Various terminology used herein can imply direct or
indirect, full or partial, temporary or permanent, action or
inaction. For example, when an element is referred to as being
"on," "connected" or "coupled" to another element, then the element
can be directly on, connected or coupled to the other element or
intervening elements can be present, including indirect or direct
variants. In contrast, when an element is referred to as being
"directly connected" or "directly coupled" to another element,
there are no intervening elements present
[0115] Also, in the description of the embodiments of the present
disclosure, the terms such as first, second, A, B, (a) and (b) may
be used. Each of the terms is merely used to distinguish the
corresponding component from other components, and does not delimit
an essence, an order or a sequence of the corresponding
component.
[0116] FIG. 1 is a perspective view of a cleaner according to an
embodiment of the present disclosure. FIG. 2 is a perspective view
showing a state where a handle part is separated from a cleaner
according to an embodiment of the present disclosure. FIG. 3 is a
view showing a state where guide frame is separated from FIG. 2.
FIG. 4 is an exploded perspective view of a cleaner according to an
embodiment of the present disclosure. FIG. 5 is a cross-sectional
view taken along line 5-5 of FIG. 1.
[0117] Referring to FIGS. 1 to 5, the cleaner 1 may include a main
body 2. The cleaner 1 may further include a suction part 5 (or
suction inlet) through which air containing dust is suctioned. The
suction part 5 may guide the air containing dust to the main body
2.
[0118] The cleaner 1 may further include a handle part 3 coupled to
the main body 2. The handle part 3 may be located on the opposite
side of the suction part 5 in the main body 2. However, the
positions of the suction part 5 and the handle part 3 are not
limited thereto.
[0119] The main body 2 may separate the dust suctioned into the
inside through the suction part 5 and store or hold the separated
dust.
[0120] In one example, the main body 2 may include a dust
separator. The dust separator may include a first cyclone part 110
capable of separating dust by a cyclone flow, e.g., helical
pattern. The first cyclone part 110 may communicate with the
suction part 5.
[0121] The air and dust suctioned through the suction part 5
spirally flows along an inner circumferential surface of the first
cyclone part 110.
[0122] The dust separator may further include a second cyclone part
140 for separating dust from the air discharged from the first
cyclone part 110.
[0123] The second cyclone part 140 may include a plurality of
cyclone bodies 142 arranged in parallel. The air discharged from
the first cyclone part 110 may be divided into the plurality of
cyclone bodies 142 and pass therethrough.
[0124] The dust separator may include a single cyclone part or more
than one cyclone part.
[0125] The main body 2 may be formed in a cylindrical shape, for
example, and an outer shape thereof may be formed by a plurality of
housings.
[0126] In one embodiment, the main body 2 may include a first
housing 10 having a substantially cylindrical shape and a second
housing 12 coupled to an upper side of the first housing 10 and
having a substantially cylindrical shape.
[0127] An upper portion of the first housing 10 may define the
first cyclone part 110, and a lower portion of the first housing 10
may define a dust bin 112 for storing dust separated from the first
cyclone part 110. The dust bin 112 may include a first dust storage
120 storing dust separated from the first cyclone part 110.
[0128] A lower side of the first housing 10 (e.g., a lower side of
the dust bin 112) may be opened and closed by a housing cover 114
that rotates by a hinge.
[0129] To seal a boundary between the first housing 10 and the
second housing 12 in a state where the first housing 10 and the
second housing 12 are coupled, the cleaner 1 may further include a
sealing member 16 and a support body 14 supporting the sealing
member 16.
[0130] Upper and lower sides of each of the first housing 10 and
the second housing 12 are open. That is, each of the housings 10
and 12 may include an upper opening and a lower opening.
[0131] The support body 14 may be formed in a cylindrical shape.
Here, an outer diameter of the support body 14 may be the same as
or less than an inner diameter of the first housing 10 so that the
support body 14 may be inserted into the first housing 10 through
the upper opening of the first housing 10.
[0132] Likewise, the outer diameter of the support body 14 may be
the same as or less than an inner diameter of the second housing 12
so that the support body 14 may be inserted into the second housing
12 through the lower opening of the second housing 12.
[0133] The support body 14 may include a communication opening 15
through which air passes or flows through. The communication
opening 15 may communicate with the suction part 5.
[0134] The sealing member 16 may be coupled to the support body 14
to surround an outer circumferential surface of the support body
14. For example, the sealing member 16 may be integrally formed
with the support body 14 by an insert injection molding process.
Alternatively, the sealing member 16 may be coupled or adhered to
the outer circumferential surface of the support body 14, such as
by an adhesive.
[0135] The main body 2 may include a suction opening 12a through
which air guided through the suction part 5 passes or flows
through.
[0136] One of the first housing 10 and the second housing 12 may
include the suction opening 12a , or the first housing 10 may form
a part of the suction opening 12a and the second housing 12 may
form another part of the suction opening 12a.
[0137] Hereinafter, an embodiment in which the second housing 12
includes the suction opening 12a will be described.
[0138] When the second housing 12 is coupled to the first housing
10, the suction opening 12a of the second housing 12 and the
communication opening 15 of the support body 14 are aligned.
[0139] The suction opening 12a is aligned with the suction part 5.
With such configuration, dust and air may be introduced into the
first cyclone part 110 through the inside of the suction part 5,
the suction opening 12a, and the communication opening 15.
[0140] In this embodiment, the support body 14 may be omitted. In
this embodiment, an upper end of the first housing 10 may be in
direct contact a lower end of the second housing 12. In addition,
dust and air may flow into the first cyclone part 110 through the
suction opening 12a after passing through the inside of the suction
part 5.
[0141] In the present disclosure, a configuration for guiding air
from the suction part 5 to the first cyclone part 110 may be
referred to as a suction passage of the main body 2.
[0142] Accordingly, the suction passage may include only the
suction opening 12a or may include the suction opening 12a and the
communication opening 15.
[0143] The main body 2 may further include a filter part 130
disposed to surround the second cyclone part 140.
[0144] The filter part 130 may be formed in a cylindrical shape,
for example, and guide air separated from dust in the first cyclone
part 110 to the second cyclone part 140. The filter part 130
filters dust from air in the process in which air flows or passes
there through.
[0145] The filter part 130 may be arranged to surround an axis Al
of a cyclone flow of the first cyclone part 110.
[0146] To this end, the filter part 130 may include a mesh portion
132 having a plurality of holes. The mesh portion 132 may be formed
of a metal material but is not limited thereto. Since the mesh
portion 132 filters air, dust may accumulate on the mesh portion
132, and thus the mesh portion 132 may need to be cleaned.
[0147] In the present disclosure, the cleaner 1 may further include
a compression mechanism 70 capable of compressing dust stored in
the first dust storage 120.
[0148] Since capacity of the first dust storage 120 is limited, the
amount of dust stored in the first dust storage 120 may accumulate
during repeated cleaning, and thus a usage time of and the number
of times the cleaner is used may be limited.
[0149] The user may cause or manipulate the housing cover 114 to
open the first dust storage 120 in order to remove dust of the
first dust storage 120.
[0150] In this embodiment, when dust stored in the first dust
storage 120 is compressed using the compression mechanism 70,
density of the dust stored in the first dust storage 120 increases,
and thus a volume thereof decreases.
[0151] Therefore, according to the present embodiment, the number
of times for emptying the dust bin 112 is reduced, and accordingly,
requiring less frequent emptying of the dust bin.
[0152] The compression mechanism 70 may also clean the mesh portion
132 during a movement process.
[0153] The compression mechanism 70 may include a movable part 750
movable in the main body 2, an operating part 710 (or manipulating
part) operated by the user to move the movable part 750, and
transfer parts 720 and 730 transferring an operation force of the
operating part 710 to the movable part 750.
[0154] The movable part 750 may be form in a ring-like shape, for
example, such that interference with a structure provided in the
first dust storage 120 may be prevented. The operating part 710 may
have a structure that the user may manually press.
[0155] The operating part 710 may be disposed outside the main body
2. For example, the operating part 710 may be located outside the
first housing 10 and the second housing 12.
[0156] At least a portion of the operating part 710 may be located
above the first housing 10. Also, at least a portion of the
operating part 710 may be located above the movable part 750.
[0157] The operating part 710 may include a pressing part 714. The
pressing part 714 may be located above the first housing 10 and the
movable part 750.
[0158] The operating part 710 may include an operating part body
712. The operating part body 712 may have a vertical length that is
longer than a horizontal width thereof. The pressing part 714 may
protrude from an upper portion of the operating part body 712.
[0159] The pressing part 714 may protrude in the horizontal
direction from the operating part body 712 in a state where the
operating part body 712 is disposed in a vertical direction.
[0160] In one embodiment, the pressing part 714 may be located
closer to an upper end than a lower end of the operating part body
712. The pressing part 714 may protrude from a position spaced
apart downward from the upper end of the operating part body
712.
[0161] The pressing part 714 may include a first portion 714a
protruding from the operating part body 712 and a second portion
714b additionally protruding from the first pressing part 714a.
[0162] The second portion 714b may protrude from a position spaced
apart by a predetermined distance in a downward direction from an
upper end 714c of the first portion 714a.
[0163] The user may move the operating part 710 in a downward
direction by pressing an upper surface 714d of the second portion
714b. Therefore, an upper surface 714d of the second portion 714b
may function as a pressing surface.
[0164] The operating part 710 may further include a coupling
projection (See 716 of FIG. 6) located on the opposite side of the
pressing part 714 in the operating part body 712.
[0165] The handle part 3 may include a handle body 30 for the user
to grip or manipulate and a battery housing 60 disposed below the
handle body 30 and accommodating a battery 600.
[0166] The handle body 30 and the battery housing 60 may be
disposed in an up-down direction, and the handle body 30 may be
located above the battery housing 60.
[0167] The handle part 3 may guide movement of the operating part
710, while covering a portion of the operating part 710.
[0168] In one embodiment, the handle part 3 may further include an
operating part cover 62. The operating part cover 62 may be located
on the side of the handle body 30 and the battery housing 60.
[0169] The operating part cover 62 may be formed integrally with
the handle body 30 and the battery housing 60 or may be formed
separately from the handle body 30 and the battery housing 60.
[0170] If the operating part cover 62 is formed separately from the
handle body 30 and the battery housing 60, the operating part cover
62 may be coupled to the main body 2.
[0171] In a state where the user grips the handle body 30 by a
right hand, the operating part 710 may be located on the left of
the handle body 30. Of course, in a state where the user grips the
handle body 30 by a left hand, the operating part 710 may be
located on the right of the handle body 30. With such
configuration, the user may more easily operate the operating part
710 by a hand that does not grip the handle body 30.
[0172] The operating part 710 may move in a direction parallel to
the axis Al of the cyclone flow of the first cyclone part 110.
[0173] For example, the axis A1 of the cyclone flow of the first
cyclone part 110 may extend in the up-down direction in a state
where the dust bin 112 is placed on the floor. Therefore, the
operating part 710 may also be moved in the up-down direction in a
state where the dust bin 112 is placed on the floor.
[0174] A slot 63 may be provided on the operating part cover 62 for
movement of the operating part 710. The pressing part 714 of the
operating part 710 may penetrate the slot 63.
[0175] A vertical length of the operating part body 712 may be
longer than a vertical length of the slot 63. A horizontal width of
the operating part body 712 may be longer than a horizontal width
of the slot 63.
[0176] The horizontal width of the pressing part 714 may be the
same as or less than the horizontal width of the slot 63. The
vertical length of the pressing part 714 may be less than the
vertical length of the slot 63.
[0177] A protruding length of the pressing part 714 may be longer
than a front-rear width of the operating part cover 62. Therefore,
the pressing part 714 may penetrate the slot 63 and may protrude
outside the operating part cover 62 through the slot 63.
[0178] The horizontal width of the operating part body 712 may be
less than the horizontal width of the operating part cover 62. The
vertical length of the operating part body 712 may be less than the
horizontal width of the operating part cover 62.
[0179] A front-rear width of the operating part body 712 may be
less than a front-rear width of the operating part cover 62. The
operating part cover 62 may form a space for the operating part
body 712 to locate. The operating part body 712 may move in the
up-down direction in a state where the operating part body 712 is
located in the operating part cover 62.
[0180] In the operating part cover 62, the operating part body 712
may move between the first position and the second position.
[0181] For example, the first position is a position when the
operating part body 712 has moved to the top, and the second
position is a position when the operating part body 712 has moved
to the bottom.
[0182] In a state where no external force is applied to the
operating part 710, the operating part body 712 may be located at
the first position. The operating part body 712 may cover the slot
63 in a state where the operating part body 712 is located at the
first position.
[0183] In one embodiment, in a state where the operating part body
712 is located at the first position, the operating part body 712
may fully cover the slot 63 inside the operating part cover 62.
Accordingly, in a state where the operating part body 712 is
located at the first position, the operating part body 712 may be
exposed to the outside of the slot 63 and a space inside the
operating part cover 62 may be prevented from being exposed.
[0184] The slot 63 may also extend in a direction parallel to the
extending direction of the axis Al of the cyclone flow of the first
cyclone part 110.
[0185] In this embodiment, since the extending direction of the
axis A1 of the cyclone flow is the up-down direction, for example,
the "up-down direction" described below may be understood as the
extending direction of the axis A1 of the cyclone flow.
[0186] Since the movable part 750 is located in the main body 2,
the operating part 710 is located outside the main body 2, one
portion of the transfer parts 720 and 730 may be located outside
the main body 2 and the other portion thereof may be located inside
the main body 2 to connect the movable part 750 and the operating
part 710.
[0187] Portions of the transfer parts 720 and 730 may penetrate the
main body 2. Portions of the transfer parts 720 and 730 located
outside the main body 2 may be covered by the handle part 3.
[0188] The transfer parts 720 and 730 may include a first transfer
part 720. The first transfer part 720 may be coupled to the
operating part 710. For example, the first transfer part 720 may
include a coupling projection 722. The coupling projection 722 may
be coupled to a projection coupling part (not shown) formed at the
operating part body 712.
[0189] The coupling projection 722 may be formed to have a vertical
length larger than a horizontal width thereof. The coupling
projection 722 may restrict relative rotation of the operating part
710 with respect to the first transfer part 720 in a horizontal
direction.
[0190] The transfer parts 720 and 730 may further include a second
transfer part 730 coupled with the movable part 750. A portion of
the second transfer part 730 may be located inside the main body 2
and the other portion thereof may be located outside the main body
2.
[0191] The second transfer part 730 may be directly connected to
the first transfer part 720 or may be connected by an additional
transfer part.
[0192] For example, FIG. 3 illustrates an embodiment where the
second transfer part 730 is directly connected to the first
transfer part 720. The first transfer part 720 may include a
coupling part 724 to which the second transfer part 730 may be
coupled.
[0193] The second transfer part 730 may extend in a direction
parallel to the axis A1 of the cyclone flow.
[0194] In the case of this embodiment, although not limited
thereto, the center of the movable part 750 may be located on the
axis A1 of the cyclone flow or a vertical line passing through the
center of the movable part 750 may be parallel to the axis A1 of
the cyclone flow.
[0195] In this embodiment, the operating part 710 is disposed at a
position eccentric from the center of the movable part 750.
Therefore, eccentricity of the movable part 750 should be prevented
in the process in which the movable part 750 moves up and down by
the operation of the operating part 710.
[0196] If the movable part 750 moves up and down in an eccentric
state, the movable part 750 may not form a horizontal state and may
not move smoothly and the movable part 750 may not move accurately
to the standby position.
[0197] When the transfer part for transferring an operation force
of the operating part 710 to the movable part 750 includes one
transfer part, a possibility that the movable part 750 is eccentric
in the process of operating the operating part 710 is high.
[0198] For example, when the operating part 710 is directly
connected to the movable part 750 or connected by a single transfer
part, a path through which the operation force of the operating
part 710 is transferred to the movable part 750 is relatively
short.
[0199] If the operating part 710 is operated in an eccentric state
with respect to a vertical line, the effect of eccentricity of the
operating part 710 may directly act on the movable part 750 so
there is a greater possibility that the movable part 750 is moved
in the eccentric state.
[0200] However, as in the present disclosure, when the transfer
part includes a plurality of transfer parts and transfers the
operation force of the operating part to the movable part 750, even
if the operating part 710 is eccentric with respect to the vertical
line in the process of operating the operating part 710, the
plurality of transfer parts may reduce the influence of the
eccentric to minimize the amount of eccentricity of the movable
part 750.
[0201] The main body 2 may further include a protruding body 180
for guiding the second transfer part 730. The protruding body 180
is, for example, present in a form protruding from the outside of
the first housing 10.
[0202] The protruding body 180 may extend in a direction parallel
to the extending direction of the axis Al of the cyclone flow of
the first cyclone part 110.
[0203] The protruding body 180 communicates with an internal space
of the first housing 10, and the second transfer part 730 may move
in the protruding body 180.
[0204] The cleaner 1 may further include a support mechanism 780
elastically supporting the compression mechanism 70.
[0205] The support mechanism 780 may include an elastic member 781
providing an elastic force to the compression mechanism 70. The
elastic member 781 may provide the elastic force to the operating
part 710 or the transfer parts 720 and 730. Hereinafter, an
embodiment where the elastic member 781 supports the operating part
710 will be described.
[0206] The elastic member 781 may be disposed spaced apart from the
second transfer part 730 in the horizontal direction. The elastic
member 781 may be, for example, a coil spring and may be expanded
and contracted in the up-down direction--but is not limited to such
mechanism.
[0207] Here, at the first position of the operating part 710 (the
position of the operating part 710 before the user presses the
operating part 710), a length of the elastic member 781 may be
longer than a length of the second transfer part 730.
[0208] When the length of the elastic member 781 is longer than the
length of the second transfer part 730, the operating part 710 may
be supported using the elastic member 781 having a low modulus of
elasticity.
[0209] In this case, a required force may be reduced when pressing
the operating part 710. In addition, when the operating part 710 is
returned to its original position by the elastic member 781, noise
that may occur as the upper end 714c of the first portion 714a in
the pressing part 714 collides with a surface forming the slot 63
of the operating part cover 62 may also be reduced.
[0210] The support mechanism 780 may further include a support bar
790 supporting the elastic member 781 so that a horizontal movement
of the elastic member 781 is limited in the vertical movement
process of the operating part 710.
[0211] The support bar 790 may be formed in a cylindrical shape
(not limited thereto). A vertical length of the support bar 790 may
be longer than a vertical length of the elastic member 781.
[0212] The elastic member 781 may be disposed to surround the
support bar 790. That is, the support bar 790 may be located at an
inner region of the coil-shaped elastic member 781. An outer
diameter of the support bar 790 may be to the same as or smaller
than an inner diameter of the elastic member 781.
[0213] One end of the support bar 790 may be coupled to the main
body 2 or a transfer part cover, which will be described later. The
first transfer part 720 may be coupled to the other end of the
support bar 790.
[0214] Here, the support bar 790 may be coupled to the first
transfer part 720 after passing through the coupling projection
(See 716 in FIG. 6). A portion of the coupling projection (See 716
in FIG. 6) may be coupled to the first transfer part 720.
[0215] The upper end of the elastic member 781 may contact the
lower side of the coupling projection (see 716 in FIG. 6).
[0216] The other end of the support bar 790 may be an upper end.
The upper end of the support bar 790 may be coupled to penetrate
the first transfer part 720.
[0217] The first transfer part 720 may move up and down along the
support bar 790. Accordingly, the support bar 790 may guide a
vertical movement of the first transfer part 720. Therefore, the
support bar 790 may be referred to as a guide bar.
[0218] The cleaner 1 may further include a transfer part cover 64
covering the transfer parts 720 and 730.
[0219] The transfer part cover 64 may be coupled to the main body 2
in a state of covering the transfer parts 720 and 730. The
operating part cover 62 may cover at least a portion of the
transfer part cover 64. In this embodiment, the transfer part cover
64 may be omitted and the operating part cover 62 may function as
the transfer part cover 64.
[0220] The transfer part cover 64 may also cover the support
mechanism 780.
[0221] The first portion 641 of the transfer part cover 64 may
cover the first transfer part 720, the support bar 790, and the
elastic member 781 at the side of the protruding body 180.
[0222] The second portion 644 of the transfer part cover 64 may be
located above the protruding body 180 and may cover the second
transfer part 730.
[0223] The transfer part cover 64 may include a slot 642 at which
the coupling projection 722 of the first transfer part 720 is
located. The slot 642 may extend in the up-down direction.
[0224] The transfer part cover 64 may have a bar coupling part 645
to which the support bar 790 may be coupled.
[0225] Meanwhile, the main body 2 may further include a suction
motor 220 for generating a suction force. The suction force
generated by the suction motor 220 may act on the suction part 5.
The suction motor 220 may be located in the second housing 12, for
example.
[0226] The suction motor 220 may be located above the dust bin 112
and the battery 600 with respect to the extending direction of the
axis Al of the cyclone flow of the first cyclone part 110.
[0227] The main body 2 may further include an air guide 170 guiding
air passing or flowing through the filter part 130 to the suction
motor 220.
[0228] In one example, the air guide 170 may guide air discharged
from the second cyclone part 140 to the suction motor 220.
[0229] The second cyclone part 140 may be coupled to a lower side
of the air guide 170. The filter part 130 may surround the second
cyclone part 140 in a state of being coupled to the second cyclone
part 140.
[0230] Therefore, the filter part 130 may also be located below the
air guide 170. The movable part 750 may be disposed at a position
surrounding the air guide 170 in a standby position.
[0231] The movable part 750 may include a cleaning part 770 for
cleaning the filter part 130.
[0232] In this embodiment, a position of the movable part 750 in a
state where the operating part 710 is not operated (an initial
position of the operating part 710) may be referred to as a standby
position (or the first position). That is, the position of the
movable part 750 when the operating part 710 is located at the
first position may be referred to as the standby position. A
position of the movable part 750 when the operating part 740 is
located at the second position may be referred to as a dust
compression position (or the second position).
[0233] At the standby position of the movable part 750, the
entirety of the cleaning part 770 may be disposed not to overlap
the filter part 130 in a direction in which air passes through the
filter part 130. For example, at the standby position of the
movable part 750, the entirety of the cleaning part 770 may be
located above the filter part 130. Accordingly, at the standby
position of the movable part 750, the cleaning part 770 may be
prevented from acting as a flow resistance in the process in which
air passes through the filter part 130.
[0234] A dust guide 160 may be provided below the second cyclone
part 140. A lower side of the second cyclone part 140 may be
coupled to an upper side of the dust guide 160. In addition, a
lower side of the filter part 130 may be seated or accommodated on
the dust guide 160.
[0235] The lower side of the dust guide 160 may be seated or
accommodated on the housing cover 114. The dust guide 160 is spaced
apart from the inner circumferential surface of the first housing
10 and divides or separates an internal space of the first housing
into a first dust storage 120 storing dust separated at the first
cyclone part 110 and a second dust storage 122 storing dust
separated at the second cyclone part 140.
[0236] The inner circumferential surface of the first housing 10
and the outer circumferential surface of the dust guide 160 may
define or form the first dust storage 120, and the inner
circumferential surface of the dust guide 160 may define or form
the second dust storage 122.
[0237] Hereinafter, the compression mechanism 70 will be described
in more detail.
[0238] FIGS. 6 and 7 are perspective views of a compression
mechanism according to an embodiment of the present disclosure.
FIG. 8 is an exploded perspective view of a movable part according
to an embodiment of the present disclosure. FIG. 9 is an exploded
perspective view of a movable part according to an embodiment of
the present disclosure. FIG. 10 is a cross-sectional view taken
along line 10-10 of FIG. 8.
[0239] Referring to FIGS. 6 to 10, the movable part 750 may include
a frame 760.
[0240] The frame 760 may be disposed to surround the axis A1 of the
cyclone flow. The frame 760 may be formed in a ring-like shape
around the axis Al of the cyclone flow.
[0241] The frame 760 may compress dust stored in the first dust
storage 120. Therefore, the frame 760 may have sufficient rigidity
for preventing deformation during a pressing process, while
effectively compressing dust during the process of compressing
dust. For example, the frame 760 may be an injection-molded
material or may be formed of a metal material (not limited to any
particular material).
[0242] A maximum diameter of the frame 760 may be less than a
diameter of an inner circumferential surface of the first cyclone
part 110. Therefore, the frame 760 may be moved up and down in a
state of being spaced apart from the inner circumferential surface
of the first cyclone part 110.
[0243] In the present embodiment, even if the movable part 750
moves up and down in an eccentric state, frictional contact of the
movable part 750 with the inner circumferential surface of the
first housing 10 (e.g., the first cyclone part 110 and/or dust bin
112) may be prevented.
[0244] In addition, when the frame 760 is spaced apart from the
inner circumferential surface of the first cyclone part 110, air
and dust suctioned into the first cyclone part 110 may flow
downward through the inner circumferential surface of the first
cyclone part 110 and the frame 760 in a state where the movable
part 750 has moved downward during the cleaning process.
[0245] The frame 760 may support the cleaning part 770. The
cleaning part 770 may be formed of an elastically deformable
material. For example, the cleaning part 770 may be formed of a
rubber material (not limited thereto).
[0246] The cleaning part 770 may be formed in a ring-like shape so
that the cleaning part 770 may clean the entirety of the
circumference of the cylindrical filter part 130 may be reduced or
prevented. As another example, the cleaning part 770 may be formed
of silicone or a fiber material.
[0247] When the cleaning part 770 is formed of an elastically
deformable material, damage to the filter part 130 when the
cleaning part 770 is in frictional contact with the filter part
130.
[0248] The movable part 750 may move from the standby position to a
dust compression position.
[0249] The cleaning part 770 may standby at a position outside the
filter part 130 at the standby position, and during a dust
compression process, the cleaning part may wipe the outer surface
of the filter part 130, while moving to the dust compression
position.
[0250] The cleaning part 770 may include a cleaning end 771a. The
cleaning end 771a may be in contact with the outer surface of the
filter part 130 during the cleaning process.
[0251] In the present embodiment, since the cleaning part 770 is
formed of an elastically deformable material, when the cleaning
part is lowered and the cleaning end 771a comes into contact with
the filter part 130, the cleaning part 770 may be elastically
deformed outward in a radial direction of the filter part 130, and
in the elastically deformed state, the cleaning end 771a may come
into contact with the filter part 130.
[0252] Therefore, when the cleaning end 770 is lowered in a state
where the cleaning end 771a is in contact with the circumference of
the filter part 130, the cleaning end 771a removes dust adhered to
the outer surface of the filter part 130.
[0253] In the present embodiment, since the cleaning end 771a is
moved in contact with the filter part 130, the cleaning part 770
may reduce eccentricity of the movable part 750 in the vertically
moving process.
[0254] In one example, in a state where the movable part 750 is
inclined with respect to a horizontal direction, a contact force
between a portion of the cleaning end 771a and the filter part 130
increases, so that the cleaning end 771a is deformed and
inclination of the movable part 750 may be reduced.
[0255] The cleaning part 770 may include a first part 771 and a
second part 772 extending upward from the first part 771.
[0256] A thickness of the second part 772 may be less than a
thickness of the first part 771. The second part 772 may be coupled
to a lower side of the frame 760.
[0257] For example, the cleaning part 770 may be coupled to the
frame 760 by an insert injection molding process.
[0258] The cleaning part 770 may further include a depressed
portion 773 recessed in a downward direction from the upper end. A
lower extending portion 761a extending from the frame 760 may be
located in the depressed portion 773. The lower extending portion
761a located in the depressed portion 773 may be aligned with the
suction opening 12a.
[0259] The frame 760 may include a frame body 761 supporting the
cleaning part 770.
[0260] At the standby position, a portion of the frame body 761 may
be in contact with the outer surface of the air guide 170. A
portion of the frame body 761 may surround an outer surface of the
air guide 170 in a circumferential direction.
[0261] The frame 760 may further include a lower extension wall 766
extending in a downward direction from the frame body 761. The
lower extension wall 766 may be rounded in the circumferential
direction of the frame 760.
[0262] The lower extension wall 766 may function to press dust
stored in the dust bin 112 in a downward direction while the
movable part 750 is lowered. The lower extension wall 766 may be
located, for example, at a portion where the outer wall 763 is
formed at the frame body 761.
[0263] The frame 760 may further include a coupling part 767
extending outward from the lower extension wall 766.
[0264] The coupling part 767 may protrude in the horizontal
direction from the lower extension wall 766. For example, the
coupling part 767 may extend in a horizontal direction from a lower
end 766a side of the lower extension wall 766. Accordingly, since
the portion to which the operation force transferred from the
transfer part is applied first acts on the lower extension wall
766, which is a position spaced apart from the frame body 761,
eccentricity of the frame body 761 may be reduced.
[0265] In addition, in the present embodiment, since the coupling
part 767 is located on the lower end 766a side of the lower
extension wall 766, an increased in height of the cleaner 1 is
prevented while a vertical movement stroke of the movable part 750
may increase.
[0266] That is, as the distance between the coupling part 767 and
the pressing portion 714 of the operating part 710 increases, the
vertical movement stroke of the movable part 750 may increase. When
the vertical movement stroke of the movable part 750 increases,
compression performance of dust stored in the first dust storage
120 may be improved.
[0267] The second transfer part 730 may be connected to the
coupling part 767.
[0268] A buffer part 734 may be coupled to the second transfer part
730. The second transfer part 730 may be coupled to penetrate the
buffer part 734. The buffer part 734 may be seated on an upper
surface of the coupling part 767 in a state where the buffer part
734 is coupled to the second transfer part 730.
[0269] The second transfer part 730 may penetrate an upper wall of
the protruding body 180.
[0270] The buffer part 734 functions to absorb a shock (e.g., force
with respect to time) that occurs when the movable part 750 comes
into contact with the upper side wall of the protruding body 180 in
the process of moving from the dust compression position to the
standby position, and accordingly, the occurrence of noise may be
reduced.
[0271] The frame 760 may further include a frame guide 765
extending in a downward direction from the frame body 761. For
example, the frame guide 765 may extend in a downward direction
from an outer circumferential surface of the first body 762a, which
will be described later.
[0272] The frame guide 765 may include a planar guide surface 765a.
The guide surface 765a may guide a spiral flow of air in the
process of air flowing through the suction part 5 (See FIG. 26).
The guide surface 765a may substantially be parallel to an
extending line extending in a tangential direction of the first
cyclone part 110.
[0273] The lower end 765b of the frame guide 765 may be located
below the contact end 771a of the cleaning part 770. The lower end
766a of the lower extension wall 766 may be located below the lower
end 765a of the frame guide 765.
[0274] Hereinafter, the frame 760 will be described in detail.
[0275] FIG. 11 is a perspective view of the frame of FIG. 9, viewed
from a direction "A". FIG. 12 is a side view of the frame of FIG.
9, viewed from a direction "B". FIG. 13 is a plan view of a frame
according to an embodiment of the present disclosure. FIG. 14 is a
cross-sectional view taken along line 14-14 of FIG. 13. FIG. 15 is
a cross-sectional view taken along line 15-15 of FIG. 13. FIG. 16
is a cross-sectional view taken along line 16-16 of FIG. 13. FIG.
17 is a cross-sectional view taken along line 17-17 of FIG. 13.
FIG. 18 is a cross-sectional view taken along line 18-18 of FIG.
13.
[0276] Referring to FIGS. 11 to 18, the frame body 761 may include
a first body 762a . The first body 762a may surround an outer
surface of the air guide 170.
[0277] An outer end 762a 1 (or upper end) of the first body 762a
based on a radial direction in the frame bodies 761 may be located
at the highest portion of the first body 762a . The radial
direction may be a direction perpendicular to the extending
direction of the axis A1 of the cyclone flow.
[0278] The first body 762a may be in contact with an outer surface
of the air guide 170, which will be described later.
[0279] Referring to FIG. 14, the first body 762a may be inclined by
a first angle .theta.1 with respect to a horizontal plane. When the
first body 762a is inclined by the first angle .theta.1, a contact
area between the first body 762a and dust stored in the first dust
storage 120 may increase in a state where the movable part 750 has
moved to the dust compression position, while air and dust
suctioned through the suction part 5 may be guided in a downward
direction.
[0280] When the contact area between the first body 762a and the
dust stored in the first dust storage 120 increases, a compression
area of the dust may increase to compress the dust stored in the
first dust storage 120 overall, thereby improving dust compression
performance by the movable part 750.
[0281] The first body 762a may be inclined outward from the lower
side to the upper side. Since the air suctioned through the suction
part 5 may flow toward the outer surface of the first body 762a ,
when the first body 762a is inclined outward from the lower side to
the upper side, a lower flow of the suctioned dust may become
relatively smooth.
[0282] An inclination angle of at least a portion of the first body
762a with respect to the horizontal plane in the circumferential
direction of the frame body 761 may be constant. A portion in which
the inclination angle is constant in the first body 762a may be in
contact with the air guide 170.
[0283] In addition, the air suctioned through the suction part 5
may smoothly flow in the circumferential direction along the
portion where the inclination angle is constant in the first body
762a. A radius R1 of the outer end 762a1 of the first body 762a may
be constant in the circumferential direction. Referring to FIG. 13,
the first body 762a may extend by an angle A section based on a
center O of the frame body 761.
[0284] The frame body 761 may further include a second body 762b
extending in the circumferential direction from the first body
762a. The second body 762b may be inclined at an angle that is less
than the first angle 81 with respect to the horizontal plane. Thus,
as the second body 762b is inclined at the second angle .theta.2, a
space may be formed between the air guide 170 and the second body
762b (See FIG. 23). The space may act as an air flow path P.
[0285] For example, the inclination angle of the second body 762b
with respect to the horizontal plane may be reduced in a direction
away from the first body 762a.
[0286] A height of the outer end of the second body 762b based on
the radial direction may be lower in a direction away from the
first body 762a than in a direction near the first body 762a.
Therefore, the second body 762b may guide the air and dust to flow
in a downward spiral direction, while providing a flow path
allowing air and dust to flow therethrough.
[0287] Referring to FIG. 15, a first portion 762b1 spaced apart by
a first distance from the first body 762a in the second body 762b
may be inclined by a second angle .theta.2 with respect to the
horizontal plane. The second angle .theta.2 is smaller than the
first angle 81.
[0288] The outer end 762b11 (or upper end) of the first portion
762b1 may be located lower than the outer end 762a1 (or upper end)
of the first body 762a.
[0289] If the outer end 762b11 of the first portion 762b1 is
located lower than the outer end 762a1 (or upper end) of the first
body 762a, a vertical gap between the second body 762b and the air
guide 170 may be increased.
[0290] When the inclination angle of the first portion 762b1 is
less than the inclination angle of the first body 762a, the first
portion 762b1 may be spaced apart from the air guide 170.
[0291] Referring to FIG. 16, a second portion 762b2 spaced apart by
the second distance from the first body 762a in the second body
762b may be substantially parallel to the horizontal plane. That
is, the inclination angle of the second portion 762b2 may be 0
(zero) or greater than 0. That is, a portion of the second body
762b may be parallel to the horizontal plane. Here, the second
distance is greater than the first distance.
[0292] The outer end 762b21 of the second portion 762b2 may be
located lower than the outer end 762b11 of the first portion
762b1.
[0293] A radius of the outer end of the second body 762b may be
substantially equal to a radius R1 of the upper end 762a1 of the
first body 762a.
[0294] Referring to FIG. 13, the second body 762b may extend by an
angle B section based on the center O of the frame body 761. The
angle B is greater than the angle A. Therefore, in this embodiment,
a circumferential length of the second body 762b is longer than a
circumferential length of the first body 762a.
[0295] The frame body 761 may further include a third body 762c
extending from the second body 762b.
[0296] Referring to FIG. 17, at a point of the third body 762c, the
third body 762c may be inclined at a third angle .theta.3 with
respect to the horizontal plane.
[0297] The third body 762c may be inclined outward from the upper
side to the lower side. For example, the third body 762c may
include an inner end 762c2 and an outer end 792c1 based on the
radial direction, and the outer end 792c1 is located lower than the
inner end 762c2. Therefore, the inner end 762c2 may be referred to
as an upper end and the outer end 792c1 may be referred to as a
lower end.
[0298] As an example, referring to FIG. 13, the third body 762c may
extend by an angle C section based on the center O of the frame
body 761. The angle C is smaller than the angle B.
[0299] The radius of the outer end 762c1 (or lower end) of the
third body 762c may be substantially equal to the radius R1 of the
upper end 762a1 of the first body 762a.
[0300] The outer end 762c1 of the third body 762c may be located
lower than the outer end of the second body 762b. The inner end
762c2 (or upper end) of the third body 762c may be located lower
than the outer end 762b11 of the first portion 762b1 of the second
body 762b. The inner end 762c2 of the third body 762c may be
located above the outer end 762b21 of the second portion 762b2 of
the second body 762b. That is, the inner end 762c2 of the third
body 762c may be located above one point of the second body 762b
and lower than another point.
[0301] The frame body 761 may further include a first contact body
762c3 inclined downward toward the center from the inner end 762c2
of the third body 762c.
[0302] The first contact body 762c3 may be in contact with the air
guide 170.
[0303] The frame body 761 may further include a fourth body 762d
extending from the third body 762c.
[0304] Referring to FIG. 18, at a point of the fourth body 762d,
the fourth body 762d may be inclined at a fourth angle 84 with
respect to the horizontal plane. The fourth angle 84 is greater
than the third angle 83.
[0305] The fourth body 762d may be inclined outward from the upper
side to the lower side. For example, the fourth body 762d may
include an inner end 762d2 and an outer end 792d1, with the outer
end 792d1 being located lower than the inner end 762d2.
[0306] The fourth body 762d may extend by an angle D section based
on the center O of the frame body 761. The angle D is smaller than
the angle C.
[0307] Referring to FIG. 13, for example, a radius R2 of the outer
end 762d1 of the fourth body 762d is smaller than a radius R1 of
the upper end 762a1 of the first body 762a. The radius R1 of the
outer end 762d1 of the fourth body 762d is smaller than a radius of
the outer end 762c1 of the third body 762c.
[0308] The radius R2 of the outer end 762d1 of the fourth body 762d
may be reduced in a direction away from the third body 762c.
[0309] The frame body 761 may further include a second contact body
762d3 inclined in a downward direction toward the center at the
inner end 762c2 of the fourth body 762d. The second contact body
762d3 may be in contact with the air guide 170.
[0310] The operation of the frame body 761 according to the shape
of the frame body 761 as described above will be described.
[0311] At the standby position of the movable part 750, the first
body 762a may face the suction opening 12a.
[0312] Since the first body 762a is in contact with the air guide
170, the air introduced through the suction opening 12a may flow in
the space between the outer surface 762a2 and the inner
circumferential surface of the first cyclone part 110 may flow.
[0313] Since the inclination angle of the second body 762b is less
than the inclination angle of the first body 762a, the inner
surface 762b12 of the second body 762b may be spaced apart from the
air guide 170.
[0314] Accordingly, a portion of the air flowing through the space
between the outer surface 762a2 of the first body 762a and the
inner circumferential surface of the first cyclone part 110 may
flow the space between the air guide 170 and the inner surface
762b12 of the second body 762b. Therefore, the inner surface 762b12
of the second body 762b serves as a guide surface.
[0315] Since the inclination angle of the second body 726b
decreases in a direction away from the first body 762a, a height of
the space between the air guide 170 and the inner surface 762b12 of
the second body may increase in a direction away from the first
body 762a.
[0316] The frame body 761 may further include a first extension
wall 763 (or outer extension wall) to restrict air from flowing
outward in the radial direction of the second body 762b in the
process in which air flows along the inner surface 762b12 of the
second body 762b.
[0317] The first extension wall 763 may extend upward from an outer
end of the second body 762b. Accordingly, air flowing along the
inner surface 762b12 of the second body 762b may be restricted to
flow outward in the radial direction of the second body 762b by the
first extension wall 763. The first extension wall 763 may define
an air flow path P to be described later. That is, the first
extension wall 763 may act as an outer wall of the air flow path P.
The first extension wall 763 may guide air in the air flow path P
to spirally flow.
[0318] The frame body 761 may further include a second extension
wall 764 (or inner extension wall). The second extension wall 764
may extend in a circumferential direction about the axis of the
cyclone flow, and the first extension wall 763 may be spaced
outward from the second extension wall 764 in the radial
direction.
[0319] The second extension wall 764 may extend upward from an
inner end of the second body 762b. The second body 762b may connect
the first extension wall 763 and the second extension wall 764. The
second extension wall 764 may act as an inner wall of the air flow
path P.
[0320] A height of the second extension wall 764 in the first
portion 762b1 may be lower than a height of the first extension
wall 763.
[0321] The third body 762c functions to guide the air flowing along
the inner surface 762b12 of the second body 762b to fall downward.
The fourth body 762d serves to guide air that has not fallen
downward from the third body 762c to finally fall downward.
[0322] FIG. 19 is a perspective view of an air guide according to
an embodiment of the present disclosure. FIG. 20 is a side view of
the air guide of FIG. 19.
[0323] Referring to FIGS. 19 and 20, the air guide 170 may include
a first guide wall 171. The air guide 170 may be fixed in position
in the main body 2.
[0324] An inner circumferential surface of the first guide wall 171
may form a flow path guiding air discharged from the second cyclone
part 140.
[0325] The first guide wall 171 may be formed in a ring-like shape,
for example and a diameter thereof may increase from the lower side
to the upper side. Therefore, the air discharged from the second
cyclone part 140 may rise smoothly.
[0326] The first guide wall 171 may include a first seating portion
171a allowing a portion of the frame body 761 to be seated or
accommodated thereon. The first seating portion 171a may be formed
as an outer circumferential surface of the first guide wall 171 is
recessed in a direction toward the center. The first body 762a of
the frame body 761 may be seated or accommodated on the first
seating portion 171a.
[0327] The first guide wall 171 may further include a second
seating portion 171b. The second seating portion 171b may be formed
as the outer circumferential surface of the guide wall 171 is
recessed in a direction toward the center. The first contact body
762c3 and the second contact body 762d3 of the frame body 761 may
be seated and brought into contact with the second seating portion
171b.
[0328] A step surface 172 is formed on the first guide wall 171 due
to the second seating portion 171b. The second extension wall 764
may be in contact with the step surface 172.
[0329] The inclination angle of the first guide wall 171 with
respect to the horizontal plane may be equal to the first angle 81
of the first body 762a, so that the first guide wall 171 and the
first body 762a may be in contact with each other.
[0330] In addition, the inclination angles of the first contact
body 762c3 and the second contact body 762d3 with respect to the
horizontal plane may be equal to the inclination angle of the first
guide wall 171. Therefore, the first body 762a may be in contact
with the first seating portion 171a.
[0331] In addition, the first contact body 762c3 and the second
contact body 762d3 may be in contact with the second seating
portion 171b.
[0332] The air guide 170 may further include a second guide wall
173 extending from a lower side of the first guide wall 171. The
second guide wall 173 may be formed in a cylindrical shape or may
be formed in a truncated cone shape with a diameter decreasing
downward.
[0333] The air guide 170 may further include a coupling body 174
extending to a lower side of the second guide wall 173. The second
cyclone part 140 may be coupled to the coupling body 174.
[0334] A coupling projection 175 may be formed on the outer
circumferential surface of the coupling body 174. The coupling
projection 175 may be accommodated in a projection recess (not
shown) of the second cyclone part 140.
[0335] The air guide 170 may further include a fastening boss 178
(e.g., fastener) extending upward from the inner circumferential
surface of the first guide wall 171. The air guide 170 may be
fastened with a component in the body 2 by the fastening boss
178.
[0336] FIG. 21 is a view showing an arrangement relation of a
movable part and an air guide at a standby position of the movable
part. FIG. 22 is a perspective view of the air guide and the
movable part of FIG. 21, viewed in a direction "C". FIG. 23 is a
perspective view of the air guide and the movable part of FIG. 21,
viewed in a direction "D". FIG. 24 is a view showing a contact area
CA in contact with the air guide in the frame body.
[0337] Referring to FIG. 21, at the standby position of the movable
part 750, the first body 762a may be in contact with the first
guide wall 171.
[0338] Referring to FIGS. 22 and 23, at the standby position of the
movable part 750, the second body 762b may be spaced apart from the
first guide wall 171. Accordingly, an air flow path P is formed
between the second body 762b and the first guide wall 171.
[0339] As described above, since the inclination angle of the
second body 762b with respect to the horizontal plane is reduced in
a direction away from the first body 762a, a height of the air flow
path P may be gradually increased.
[0340] The height of the upper end 763a of the first extension wall
763 may be lower in a direction away from the first body 762a than
towards the first body 762a. Accordingly, a distance between the
upper end 763a of the first extension wall 763 and the first guide
wall 171 may be gradually increased.
[0341] The contact area CA in contact with the air guide 170 in the
frame 760 is illustrated in FIG. 24, and an area other than the
contact area CA may form an air flow path in relation to the air
guide 170.
[0342] FIG. 25 is a view showing a state of air and dust flowing in
a state where the movable part moves to the dust compression
position in FIG. 5. FIG. 26 is a cross-sectional view taken along
lines 26-26 of FIG. 5. FIG. 27 is a cross-sectional view taken
along line 27-27 of FIG. 5. FIG. 28 is a cross-sectional view taken
along line 28-28 of FIG. 27.
[0343] Referring to FIGS. 25 to 28, the suction part 5 includes a
flow guide 52 for guiding a flow of air and dust, and the frame
guide 765 may extend in the same direction as the extending
direction of the flow guide 52 or in a direction parallel
thereto.
[0344] For example, an extending line A4 extending in a tangential
direction of the first housing 10 may be parallel to an extending
line A3 of the frame guide 765.
[0345] Therefore, the air introduced into the first cyclone part
110 through the suction opening 12a may change in a flow direction
by the frame guide 765 and flow along the inner circumferential
surface 110a.
[0346] At the standby position, the second body 762b may be spaced
apart from the first guide wall 171 and the upper end 763a of the
first extension wall 763 may be spaced apart from the first guide
wall 171, a portion of the air flowing along the inner
circumferential surface 110a of the first cyclone part 110 may flow
to the air flow path P.
[0347] That is, while a portion of the air introduced through the
suction opening 12a flows along the air flow path P and another
portion thereof may spirally flow along the inner circumferential
surface 110a of the first cyclone part 110, the air may be
separated from dust.
[0348] In this disclosure, the air flow path P above the frame body
761 may be referred to as an upper flow path and a flow path
located below the frame body 761 may be referred to as a lower flow
path.
[0349] In addition, a space between the frame body 761 and the
inner circumferential surface of the housing (e.g., the inner
circumferential surface 110a of the first cyclone part 110) may be
referred to as a communication flow path connecting the upper flow
path and the lower flow path. Air and dust on the upper flow path
may move to the lower flow path through the communication flow
path.
[0350] The first body 761a may be disposed to face the suction
opening 12a. Therefore, it is possible to prevent air and dust
suctioned through the suction opening 12a from directly flowing
into the air flow path P.
[0351] The air introduced into the air flow path P may flow along
the second body 762b. Air flowing along the second body 762b may be
prevented from flowing in the radial direction of the second body
762b by the first guide rib 763.
[0352] Since the second extension wall 764 may be in contact with
the step surface 172 of the air guide 170, air is prevented from
flowing between the second body 762b and the second extension wall
172.
[0353] Referring to FIG. 27, at the standby position of the movable
part 750, the frame body 761 may be spaced apart from the inner
circumferential surface 110a of the first cyclone part 110, for
example, of the inner surface of the housings 10 and 12.
[0354] Therefore, in the process in which the movable part 750
moves in an up and down direction, the movable part 750 may be
prevented from rubbing with the inner surfaces of the housings 10
and 12 and air or dust may fall downward through a space between
the movable part 750 and the inner surfaces of the housings 10 and
12.
[0355] The movable part 750 may be operated by operating the
operating part 710 by the user, and thus the user may operate the
operating part 710 while the cleaner 1 is operating (suction motor
220 is operating).
[0356] Referring to FIG. 25, during the operation of the cleaner 1,
the movable part 750 may move in a downward direction by the
operation of the operating part 710.
[0357] A case where the movable part 750 has moved to a position
lower than the lower end of the suction opening 12a will be
described.
[0358] Since the movable part 750 is spaced apart from the inner
circumferential surface 110a of the first cyclone part 110 at a
position where the movable part 750 has moved in a downward
direction, air and dust suctioned through the suction opening 12a
may move more smoothly downward through a space between the movable
part 750 and the inner circumferential surface 110a of the first
cyclone part 110.
[0359] At the position where the movable part 750 has moved
downward, dust D may accumulate in the air flow path P formed by
the movable part 750.
[0360] The movable part 750 may rise in a state where dust D
accumulates in the air flow path P of the movable part 750. When
the movable part 750 rises in the state where dust D accumulates in
the air flow path P of the movable part 750, the movable part 750
may not be located at a regular position, and thus the movable part
750 may act as a flow resistance of air flowing through the suction
opening 12a.
[0361] For example, if large amount of dust D is located in the air
flow path P of the movable part 750 and the state where the dust D
is not removed from the air flow path P is maintained, the dust may
come into contact with the first guide wall 171, and in this case,
the first body 762a may be spaced apart from the first guide wall
171.
[0362] Here, air suctioned through the suction opening 12a may flow
between the first body 762a and the first guide wall 171.
[0363] If the air suctioned through the suction opening 12a flows
between the first body 762a and the first guide wall 171, air
presses the first body 762a in a downward direction.
[0364] Here, even if the user does not operate the operating part
710, the movable part 750 may move in a downward direction, and
thus, dust separation performance may be deteriorated by air flow
resistance.
[0365] In addition, when the first body 762a is not in contact with
the first guide wall 171, the movable part 750 is located in an
inclined state without maintaining level overall, and thus a
downward movement of the movable part 750 is not smooth when the
user operates the operating part 710.
[0366] However, according to the present disclosure, even if the
movable part 750 rises in a state where the dust D accumulates in
the air flow path P of the movable part 750, a portion of air
suctioned through the suction opening 12a may flow through the air
flow path P.
[0367] When air flows through the air flow path P, the dust D may
be moved in the air flow path P by air.
[0368] In the present embodiment, since the vertical width of the
air flow path P gradually increases, the dust D in the air flow
path P may be more easily moved together with the air.
[0369] In addition, referring to FIGS. 27 and 28, the dust D
flowing along the second body 762b may fall downward along the
third body 762c due to the increase in the inclination angle of the
third body 762c. Even if the dust D does not fall downward along
the third body 762c, the dust may fall downward on the fourth body
762d side.
[0370] In the case of this embodiment, since the radius at the
outer end 762d1 of the fourth body 762d is the minimum at the frame
body 761, a gap between the fourth body 762d and the inner
circumferential surface 110a of the first cyclone part 110 is
maximized.
[0371] In addition, since the inclination angle of the fourth body
762d is greater than the inclination angle of the third body 762c,
dust may more easily fall downward along the fourth body 762d.
[0372] Therefore, according to the present embodiment, in the
cleaning process, even if the movable part rises with dust
accumulating on the upper part of the movable part, air flowing
along the air flow path of the movable part may move the dust and
the moved dust may fall downward, and thus the movable part may be
stably located at the regular position.
[0373] In the above embodiment, it is described that the frame body
761 includes the first body to the fourth body 762a, 762b, 762c,
and 762d, but alternatively, the frame body 761 may include the
first body to the third body 762a, 762b, and 762c.
[0374] In this case, the radius of the third body 762c may be less
than the radius of the first body 762a and the dust D on the air
flow path P may fall downward through the space between the third
body 762c and the inner circumferential surface 110a of the first
cyclone part 110.
[0375] In the present disclosure, the second body 762b forming the
air flow path P in the frame body 761 may be referred to as a flow
path body. The flow path body may include a first portion inclined
by a first angle with respect to the horizontal plane and a second
portion extending from the first portion and inclined by a second
angle smaller than the first angle with respect to the horizontal
plane.
[0376] Further, in the present disclosure, the third body 762c may
be referred to as a third portion and the first body 762a may be
referred to as a fourth portion to correspond to the first portion
and the second portion of the second body 762b.
[0377] The third body 762c or the third body 762c and the fourth
body 762d guides the dust in the air flow path P to fall downward,
and thus the third body 762c or the third body 762c and the fourth
body 762d may be referred to as guide bodies.
[0378] When the frame body includes only the third body 762c, a
width of at least a portion of the third body may be reduced in the
circumferential direction. In this case, for example, a distance
between a point of the third body 762c and the inner
circumferential surface 110a of the first cyclone part 110 is
greater than a distance between the second body 762b and the inner
circumferential surface 110a of the first cyclone part 110.
[0379] It will be apparent to those skilled in the art that various
modifications and variations may be made in the present disclosure
without departing from the spirit or scope of the disclosures.
Thus, it is intended that the present disclosure covers the
modifications and variations of this disclosure provided they come
within the scope of the appended claims and their equivalents.
